The internet speed was normal at first, and it slowed down immediately after about a minute

I think there's something wrong with your network cable, and those 5 seconds are probably just the cache of the web page.

If it is not possible to change the network cable, it is recommended to find customer service or professional people.

The solution to the problem can refer to the NetEase blog.

A couple of great ways to do it. How to increase internet speed:

You can reset the QoS packet.

windows

XP provides users with a new set of network connection programs"quality

ofservice (QoS packets).", and install Windows

XP, the system sets it as the invoker by default, and retains about 20% of the band search width. In other words, if you don't use QoS, you're losing 20 percent of bandwidth.

In fact, the program is only effective for large business networks, especially for individual users or small business users.

Not much for ADSL users. It's best to disable this program, doing so can increase the speed of your network connection by about 20 percent.

Here's how it should be:

1. Click "Start" - >Run" and enter it in the text box""to start"Group Policy"Utensil.

2. In the tree directory on the left, double-click "Computer Configuration|".

Manage templates. Network directory entry, select the QoS Packet Invoker entry.

3. On the right side of the window, click the "Limit Retained Bandwidth" tab item. Select "Properties" to open the properties dialog box, select "Enabled", enter the number "0" in the "Bandwidth limit" box, (note that just disabling it without setting the reserved bandwidth to "0" will not free up the occupied bandwidth), and finally click "Confirm" to exit the Group Policyr.

It's going to be a lot faster.

Please give points.

If it's always been like this, there are several possibilities:

1. It may be because the configuration of your machine is not good (you should consider upgrading the hardware);

2. It may be that the bandwidth of your bridge access is not enough and the Internet speed is slow. If it's been like this recently:

If it's something like this recently, it could be:

1. It may be poisoned, you can find suspicious things in the "Task Manager" of Minsocks; Or use the "Internet Assistant" to analyze and process;

2. It may be that the free space of your hard disk is not enough to leak and bend, and you should clean up the disk;

3. It may be that you have too many "temporary Internet files", consider cleaning up;

4. Is the webpage you are opening too big? You can just open the text;

In addition, some malicious** may also affect the speed of opening a web page.

Clean up your computer with a tool such as Internet Assistant or Optimizer.
